The Dilution project is a long-term artistic research project revolving around the subject of anti-psychiatry and the democratic movement in the Netherlands in the 1970s. It focuses on the heritage and the actuality of the Nieuw Dennendal experiment, as well as the legacy of psychologist Carel Muller who developed the idealistic and utopian concept of 'dilution' in collaboration with the progressive architect Frans van Klingeren. This groundbreaking experiment aimed at bringing together healthy and mentally ill people to overcome the formation of a polarised and hierarchical society.

We have been developing artistic research projects at the following artist in residencies Kunsthuis Syb (Beetsterzwaag 2014), Het Vijfde Seizoen (Den Dolder 2015) and Instituto Buena Bista (Curacao 2016). In each of the projects we have been working together with patients from mental health care institutions, and made art works consisting in drawings, ceramics, photography and installations. Each residency period has been concluded with a video.

In May 2017 the publication 'Homestead of Dilution' was presented, designed by Bardhi Haliti and published by Onomatopee. The publication functions as a reader and presents different perspectives on the concept of 'dilution'. It includes extensive documentation by Domenico Mangano & Marieke van Rooy, essays and interviews by John Foot, Ilaria Gianni, Niekolaas Johannes Lekkerkerk, Marieke van Rooy, Aaron Schuster, and Esther Vossen.
The Dilution project was made possible with support of the Mondrian Fund.
